Abstract: 439,654. Gas meters. WHITE SMITH, I. N., 20, Queen's Road, Urmston, near Manchester. Sept. 7, 1934, No. 25820. [Class 54] [See also Group XXII] The cast metal gas passages and valve seatings of a gas meter are secured to the sheet metal diaphragm chambers by a casting process during which the diaphragm chambers may be secured to the meter casing members. In constructing the meter shown in Fig. 1 two cup-shaped members a of pressed tinned sheet iron are placed in moulds and castings c comprising gas passages d, e, f, k, and having spigots m on their upper surfaces are formed in situ. The members a are next placed in pressed metal boxes p, q formed with inturned flanges r, and the parts are secured together by casting valve seatings 21 on to the castings c. The flexible diaphragms 22 and motiontransmitting mechanism are then secured to the members a and the boxes p, q and a partition plate 20 are clamped together by screws or tie bolts to form the measuring chambers. The passages k register with a hole in the plate 20 and connect the passages e with a gas outlet pipe 11. The valves and registering mechanism may now be fitted and the meter completed by sealing in position the valve box cover. Fig. 4 shows one method of securing together the boxes p, q and valve cover consisting of loose screws u passing through spacing tubes t and holes in the flanges r, the metal around which is plunged inwards and screw-threaded. Alternatively the bolts may pass through metal fillets and bosses which are anchored by being cast around the outwardly turned metal of the holes. The boxes p, q may alternatively be formed of seamed sheet metal, the folded corners being sealed by cast metal x, Fig. 7, or by means of screws engaging holes formed in bosses y, Fig. 9, cast around the outwardly turned metal of the holes. The castings c may alternatively be formed while the cups a are in position in the metal boxes or the gas passages may be formed in pressings which are secured to the casing member or members in a mould or die by casting. In a modification shown in Fig. 10 the diaphragm chambers 2, 3 are formed by open-ended pressings projecting from a division plate 20 and are secured by screws 24 to the gas passage units 7, 8, which are die-cast to the outer casings 5, 6. The whole is held together by screws 10. The outlet passage is formed by a separate unit 11 secured by a flange 12 to a die-cast seating on the lower portion of the meter. In a further modification the complete outer casing, except for the top and bottom covers, is made up in one piece and the measuring chambers consist of pressed pans. The diaphragms are gripped at the joints between the pans. The gas passages are die-cast in position adjacent to openings in the pans and register with passages in a valve-plate casting to which they are secured by screws.

Title: Improved means for controlling the transmission of electrical impulses
IPC: G08C19/20
Filed: 1919-10-27
Abstract: 158,085. Sykes' Interlocking Signal Co., Ltd., W. R., and Tarrant, R. W. Oct. 27, 1919. Order - type apparatus.-Relates to switches for transmitting a definite number of impulses of current, either positive or negative as required. A switch blade is deflected by cam-action from a hand-turned wheel, the direction of turning determining whether the the deflection is towards a positive or a negative contact, and the amount of turning determining the number of times such contact is made. According to Fig. 1, two switch blades j<1>, j<2> are operated in this manner. Specially shaped cams h<1>, h<2> mounted on the respective blades are encountered by pins mounted on a wheel (not shown) which is rotated through gearing by a handle f, disposed, as shown in Fig. 4, on the outside of a casing a. Clockwise rotation causes the blades to be deflected into contact with stationary terminal screws k<1>, k<2>; counter-clockwise rotation deflects them into contact with screws k<1x>, k<2x>. Electric connections shown in Fig. 5, enable positive or negative current impulses to be sent from a battery B to a receiving instrument M. A numbered dial D having an index pointer c' attached to the wheel axle is provided on the outside of the casing. Definite stops corresponding to each member are ensured by notches on the edge of the wheel co-operating with a roller mounted on a spring-controlled lever. The same effects may be obtained from a single deflected blade connected to two batteries. In a modified apparatus there is an electromagnetic lock for preventing the wheel from being rotated too fast, and a different disposition of contact making parts in combination with spring-controlled detents to prevent the rotation from being reversed between two consecutive index stops. The invention is applicable for controlling the step-bystep electric motor apparatus described in Specification 139,038, [Class 35, Dynamo-electric generators &c.].
